Performance analysis of path selection routing protocol for UVANET based on geographical multicast routing algorithm

Urban Vehicular Ad hoc Networks (UVANETs) are the most important form of mobile ad hoc networks (MANETs). It has been broadly used in intelligent transportation system (ITS) to supply safety and comfort services to the passengers and drivers and also provide security/privacy using vehicle-to-vehicle and vehicle-to-road side unit (RSU) communications. In UVANETs, this research which maintains the security of the sensitive information shared between vehicles and end-users and tested on different types of attacks and provide possible solutions. And different emerging open challenges along with the security threats are identified and detected and the power of each node are also managed. This research proposed geographical multi cast network mode to analysis the performance of path selection routing protocols (PSRP) for UVANET because geographical multicast network mode uses central coordinator or it constructs virtual central coordinates. Due to these benefits geographical multicast routing algorithm (GMRA) is used to handle security issue, fault detection technique and power management. To simulate the proposed scheme, for performance analysis network simulator-3(NS-3) version-3.23 is used. Simulation results show that, the PDR for five CBR connections, GMRA is 4% and 7% better than GPSR and AODV routing protocols, respectively. Similarly one can observe the same advantages of GMRA at 10 CBR and 15 number of CBR connections. The packet loss of GMRA is enhanced by 10% and 7% than GPSR and AODV routing protocols respectively. The delay of GMRA for the three CBR connections are lower than GPSR and AODV routing protocols. Over the past few years, the technology of vehicular ad hoc networks (VANETs) has been a significant topic of research. The idea of creating a network of cars for a particular need gave rise to the ad-hoc nature of VANET networks. VANETs are widely recognized as dependable networks used by cars in urban settings for communication. Security for VANET should be prioritized on a par with security for other computing networks. All apps created for vehicular networks must be safeguarded from malicious manipulation because to the very sensitive nature of the information broadcast <i>via</i> VANET. Thus, creating a dynamic routing protocol that can assist in spreading information from one node (vehicle) to another is one of the key issues in the design of vehicular ad-hoc networks. This research presented Path Selection Routing Protocol for UVANET based on geographical multicast routing algorithm to overcome this problem and analyze UVANET performance.
